Research and breakthroughs
Curated developments in cell biology, aging, AI medicine and medical technology—clearly separated into established knowledge, promising findings and early-stage research.
Scientists map senescent cells across the lifespan
A large-scale atlas is helping researchers identify where non-dividing cells accumulate and how they may contribute to age-related conditions.
Read NIH summary ↗FDA tracks AI-enabled medical devices
The list provides public information about authorized devices and helps users examine intended use and decision summaries.
Open FDA list ↗AI medical devices require ongoing monitoring
Performance can change when data, populations, clinical protocols or environments shift. Postmarket monitoring is part of responsible deployment.
Read FDA program ↗Physical activity supports function at every age
NIA emphasizes aerobic, strength and balance activity, with adaptations based on ability and health status.
Read NIA guide ↗Biomarkers need context
A marker may be useful for research, screening or tracking without being a direct target or a complete measure of “cellular age.”
